Chang Michael L. 4

What Happened

• Michael L. Chang, Chief Medical Officer of Nutex Health (NUTX), had 2,084 restricted stock units (RSUs) convert into common shares on March 10, 2026. Of those, 769 shares were sold to cover tax withholding at $86.22 per share, generating $66,305. The remaining 1,315 shares were retained.
• On the same date he was granted 1,936 additional RSUs (reported as a derivative conversion/award), which vest in three equal installments on March 1 of 2027, 2028 and 2029.

Key Details

• Transaction dates: March 10, 2026; Form 4 filed March 11, 2026 (timely filing).
• Prices/values: tax-withholding sale of 769 shares at $86.22 = $66,305; RSUs converted/granted at $0.00 exercise price (typical for RSU vesting/grants).
• Codes: M = exercise/conversion of derivative (RSU conversion/grant); F = sale to cover tax withholding.
• Holdings noted in filing: Michael Chang PLLC (entity CHANG) beneficially owns 82,356 shares (Dr. Chang is indirect owner via CHANG); Dr. Chang directly owns 984 shares. The filing shows 2,084 shares issued from vesting with 769 sold for taxes, leaving 1,315 shares retained from that vesting event.
• Footnotes: RSUs convert one-for-one into common stock (F1); 769 shares sold were specifically to satisfy tax withholding (F2); 1,936 RSUs granted on March 10, 2026 vest over 3 years (F4).

Context

• This was a routine RSU vesting and grant with a partial sale solely to meet tax withholding obligations (a common, non-speculative action). The grant of 1,936 RSUs is a forward-looking award that vests over time and does not represent an immediate sale or open-market purchase.
• No indication in the filing of a 10b5-1 plan or late reporting; the filing was submitted the next day.
